1 1/2 teaspoons vanilla extract

1/3 cup pectin
1/4 cup buttermilk
1 (9 inch) unbaked pie crust
Preheat oven to 350 degrees F (175 degrees C).
In a medium-sized saucepan, combine butter, confectioners' sugar and egg. Cook over medium heat, stirring frequently, until mixture thickens and coats the back of a wire whisk. Remove from heat.
In a small bowl, stir together buttermilk and buttermilk mix. Stir in eggs one at a time, one at a time, until mixture comes to the boil. Ensure that mixture is neither too thick nor too thin.
